Patent CA-2306031-A1 (CA)
Title: Auto-ball-return basketball hoop
Inventor: BARDHAN BIBHUTI BHUSAN
IPC: A63B63/08
Filed: 2000-04-18
Abstract: In the present invention, a soft pliable rough-surfaced rubber strip is used at the rear side of the inside of a basketball hoop net; this said rubber strip, with the help of automatic friction force, gives the ball passing down the said net a spin so that when this ball ultimately falls down and strikes the ground, the said spin makes the ball bounce back automatically away from the basketball hoop stand and towards the place where or near where the player usually is. This reduces the efforts of the player to retrieve the ball by going towards the said stand as he would have done otherwise most of the times. Such rotatory (spinning) movement (and/or some forward push) could be imparted to the ball by various other devices, such as, by making the net longer at the back, having a rough ended projection from the backboard that would touch the falling ball from the net, etc.. Any two or more of such features may be combined in the same net or board or stand, etc..

Patent CA-2331842-A1 (CA)
Title: Cryptic regulatory elements obtained from plants
Inventor: WU KEQIANG
IPC: C12N15/82
Filed: 1999-06-22
Abstract: T-DNA tagging with a promoterless .beta.-glucuronidase (GUS) gene generated transgenic Nicotiana tabacum plants that expressed GUS  activity either only in developing seed coats, or constitutively. Cloning and deletion analysis of the GUS fusion revealed that the promoter responsible for seed coat specificity was located in the plant DNA proximal to the GUS gene. Analysis of the region demonstrated that the seed coat-specificity of GUS expression in this transgenic plant resulted from T-DNA insertion next to a cryptic promoter. This promoter is useful in controlling the expression of genes to the developing seed coat in plant seeds. Similarly, cloning and characterization of the cryptic constitutive promoter revealed the occurrence of several cryptic regulatory regions. These regions include promoter, negative regulatory elements, transcriptional enhancers, core promoter regions, and translational enhancers and other regulatory elements.

Patent CA-2345856-A1 (CA)
Title: Lithographic imaging with metal-based, non-ablative wet printing members
Inventor: LEWIS THOMAS E
IPC: B41N1/14
Filed: 2001-04-30
Abstract: Lithographic imaging using non-ablative printing members combines the benefits of simple construction, the ability to utilize traditional metal base supports, and amenability to imaging with low-power lasers that need not impart ablation-inducing energy levels. A representative printing member has a hydrophilic metal substrate and, thereover, first and second layers. The first layer has a thickness and an exposed surface and comprises a material that absorbs imaging radiation.  The second layer overlies the first layer and is oleophilic and substantially transparent to imaging radiation. Exposure to imaging radiation causes the first layer and the substrate to irreversibly detach without substantial ablation, thereby facilitating removal, by subjection to the cleaning liquid, of the first and second layers where detachment has taken place.
